Ross Wolf came out of literally nowhere in 2013. Like, he literally skipped over about five guys who were slotted in front of him to get a spot start early in the season and he was successful against the Oakland A's.
Pitching in the bigs for the first time since 2010 (before that it had been since 2007), Wolf got a win against the A's in his first game in three years. He also got a win in another spot start against Baltimore before getting shelled by the O's a week later.
Wolf's other appearances were out of the bullpen and he compiled a 1-3 record with a 4.15 ERA in 47 2/3 innings.
He was recently designated for assignment by the Rangers but was signed back to a minor-league deal after clearing waivers, meaning he'll be with the Rangers in spring training with a chance to make the big-league club again out of the bullpen.
He'll most likely be a guy that hangs around Triple-A and comes up for the occasional spot start, if necessary, but he did make a decent showing for himself in 2013 and could be a nice fit with the Rangers moving forward.
